Derived section properties
Integrated from the section's own outline including the root and toe radii, whose arcs are integrated analytically rather than approximated by facets. For HP 305 x 79 the computed area agrees with the published value to 0.01% and Ix to 1.44%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Wel,x | 1,099,156 mm³ |
| Elastic modulus, Wel,y | 347,675 mm³ |
| Plastic modulus, Wpl,x | 1,218,491 mm³ |
| Plastic modulus, Wpl,y | 531,214 mm³ |
| Radius of gyration, rx | 127.9 mm |
| Radius of gyration, ry | 72.8 mm |
Wel is the elastic modulus and Wpl the plastic modulus, following Eurocode 3 notation.
